There are a few things you need in order to build a wooden car. The first is alder wood, which is the most common type of wood used for cars. You can find this type of wood at most lumberyards and home improvement stores. Next, you’ll need some screws and nails. You’ll also need a saw, drill, and saw blade. In order to cut the wood, you’ll need to use a saw blade that’s been sharpened to a fine point. Finally, you’ll need some screws and nails to hold the car together while it’s being built.
